CAR-STRAP.

SPECIFICATION forming part of Letters Patent No. 605,075, dated June 7, 1898.

- Application filed February 15, 1898. Serial No. 670,376. (No model.)

To aflZ whom it may concern.-

Be it known that I, FREDERICK WILLIAM BURKE, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Car- Straps, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same. 7 V

This invention relates to car-straps and it has for its object to provide a simple and improved device of this character in which slipping of the strap upon the sustaining-bar will be entirely avoided and whereby greater security in the general operation or function of the strap is insured.

The invention is fully disclosed in the following specification, of which the acco npan ying drawings form a part, in which the separate parts of my improvement are designated by the same letters of reference in each of the views, and in which Figure 1 is a side view of a car-strap mechanism embodying my invention, and Fig. 2 is a vertical transverse sectional view.

Referring to the drawings, A- designates the bar or rod upon which the strapB is mounted. The rod A extends longitudinally of the car and is sustained in position by suitable hangers. Ordinarily the strap is simply looped over the sustaining-rod, the latter being smooth and cylindrical.

In my invention the rod or bar A is provided with a corrugated or toothed top edge or surface a, andthe strap B is independently carried upon a clamp C, havinga corrugated or toothed bottom edge or surface 0, corresponding to the edge a and adapted to bind in connection therewith.

It will be understood that the clamp or block 0 is movable or adjustable with relation to the edge a of the rod A. The strap is preferably secured to the sides of the clamp O, as shown at b I), this connection being preferably fixed and not piv'otal, and the rod or bar A is inclosed within the body or loop portion of the strap beneath the clamp or block C, as shown inFig. 2. The rod A 5oand clainp'C are preferably square or rectangular in cross-sectional contour, whereby the corrugated or toothed engaging edges are horizontal or flat. The corrugations or teeth upon the respective interlocking edges of the gated 'or toothed top edge of the rod will effectively maintain a fixed position of the strap and entirely avoid any liability of slipping, while weight or strain upon the strap in a downward direction serves to firmly bind or lock the clamp in fixed position. By lifting the strap the clamp or block can be conveniently elevated above the sustaining rod or bar, so that the strap may be adjusted to a different position with relation to the latter.

Having fully described my invention, I claim as new and desire to secure by Letters Patent 1. An improved car-strap device, comprising a sustaining rod or bar, and a supportingstrap carried upon a clamp or block adapted to interlock with said sustaining-rod, substantially as and for the purpose set forth.

2. An improved car-strap device, comprising a sustaining rod or bar, a clamp or block adapted to interlock with said rod or bar, and

a supporting-strap carried by and depending from said clamp or block and embracing the rod or bar, substantially as and for the purpose set forth. I

3. An improved car-strap device, comprising a sustaining rod or bar provided with a corrugated or toothed top edge, a.clamp or block having a corresponding corrugated or toothed bottom edge adapted to interlock with the top edge of the rod or bar, and a supporting-strap carried by said clamp or block, substantially as and for the purpose set forth.

4. An improved car-strap device, comprising a sustaining rod or bar having a corrugated or toothed top edge, a clamp or block having a correspondin g'corru gated or toothed bottom edge adapted tointerlock with the top edge of the rod or bar, said clamp being movtoo able or adjustable with relation to said susmy invention I have signed my name, in prestaining" member, and a supporting-strap eonence of the subscribing Witnesses, this 10th nected with the sides of the clamp or block day of February, 1898. and depending therefrom and embracing the FREDERICK ILLIAM BURKE,

5 sustaining member, substantially as and for Vitnesses:

the purpose set forth.

In testimony that I claim the foregoing as SHERMAN D. RICHARDSON, JEREMIAH M. DWYER.
